Accounting

You can do Bachelors in Arts this has no accounts and no maths.

Definitely no, you have already scored good marks in accounts, Its just a wastage of money and instead of that you should start listing for colleges according to the subject you opted or.

DK Goel by Arya publications is the best book other than NCERT and in terms of 12th board for exams.

Hello Clifford Chanda, it's very nice to hear from you that you are interested in doing more than one course at a time. A word of caution. In India, attendance in college at certain levels, roughly 75%, is a must to get a hall ticket for appearing in the exam. If you can manage this then you can do it. Else you can think of doing one course physically and the other via distance education mode. Best wishes to you.
